periodic table

What are the three main groups of the periodic table?

• groups

• metal

• nonmetals

• metalloids

• periods

What are the vertical columns on the periodic called?

• groups

• periods

• nonmetals

• metals

• metalloids

What do the vertical columns on the periodic table tell us?

• The number of orbitals

• The number of valence electrons (electrons on the outer most shell)

What are the horizontal rows on the periodic table called?

• periods

• groups

• metals

• nonmetals

• metalloids

What do the horizontal rows on the periodic table tell us?

• The number of orbitals

• The number of valence electrons (the electrons on the outer most shell)

What does the number of proton tell us?

• electrons

• atomic number

• atomic mass

• neutrons

How do you calculate the number of neutrons? *

• Mass = Atomic number - Neutrons

• Mass - Atomic number = Neutrons

• Atomic number = Neutrons

What is the name of the element? (Periodic table will be needed)

• sodium

• magnesium

• vanadium

What group and period does this element belong in? *

• period 1 and group 3

• period 3 and group 1

• period 2 and group 3

• period 3 and group 2

How many valence electrons does the element have?

• 1

• 2

• 3

• 4
